In your life, you have at least one relative stranger whom youâ€™ve grown close to. Maybe itâ€™s a doorman. Maybe itâ€™s the cashier at the local bodega. Maybe itâ€™s the guy who works in the next cubicle over. So what if you only know their first name, and youâ€™ve never had a conversation that exceeded 45 seconds? Over months of opened doors, midnight candy bars, and borrowed staplers, youâ€™ve become quite familiar. You have a bond, a friendship, that can only be built over countless moments of tiny social friction. So why would things work any differently online?
